Technical details
Endpoint
POSThttps://x402.quicknode.com/dot-mainnet/When to prefer
Use this endpoint when you need to interact specifically with the Polkadot (DOT) mainnet blockchain via JSON-RPC, such as querying chain state, submitting extrinsics, or reading block and account data. Prefer this over self-hosted nodes for reliability and over other chain endpoints when the target network is Polkadot mainnet specifically.
